To further improve the undergraduates’experimental skills in organic synthesis and innovation ability,this paper introduces the synthesis and characterization of donor-acceptor typed aggregation-induced emission(AIE)luminogen by using triarylamine and pyrazine building blocks.By following this experiment,the luminescence mechanism in organic fluorescence molecules and their potential applications,especially for AIE molecules,are illustrated.Furthermore,this is not only beneficial to improve students’experimental skills,such as vacuum distillation,extraction,drying,and column chromatography,but also promote their understanding in instrumentations,such as nuclear magnetic resonance instruments,high resolution mass spectrometers,ultraviolet-visible spectrophotometers,and spectrofluorometer.The significant improvement in experimental ability and innovation ability for students can be achieved through a good combination of classroom study and comprehensive experimental learning,thus finally resulting in a foundation to further cultivate their innovation capability in the scientific research in future.
